NCIS: LA: The Gang Gets a Christmas Surprise

LA crew got the best Christmas present any of them could ask for on Sunday's holiday episode, with Kensi (Daniela Ruah) making her big return to the office... for one evening, at least.

Kensi's still not physically strong enough to come back to the force full-time, as evidenced by her training sessions with Nell (Renee Felice Smith), but she did snap out of her funk long enough to drop by the office holiday party with homemade cookies to the surprise of everyone, including Deeks (Eric Christian Olsen).

Callen (Chris O'Donnell) invites her to Christmas dinner, the first one he'll be spending with his father, and if that's not an indication that sparks are flying between these two, I don't know what is.

I think it's a safe assumption that Hetty's investigation has not turned up any leads so far.

[...] in Nell and Eric (Barrett Foa) developments, Nell is thrilled to hear that she got into a Women in Technology mentorship program, but unfortunately, it coincides with a Dickens fair in which Eric is performing.

To reiterate, she gives him a gift of a pendulum clock, which will keep time on its own but fall into sync with another pendulum clock if they're placed on the same wall.
